Microcontroller operation using Zinc-air battery

Fri, 2018-04-27 00:09 -- Hassan

Hi,
Can the DA14580 chip operate using a Zinc-Air battery?
The product catalog (http://www.mouser.com/ds/2/713/da14580-family-product-brief-772320.pdf) states "it can run from voltages as low as 0.9 V: ideal for running from single-cell or Zinc-air batteries." But what about the current. Can the Zinc-Air battery provide enough current to supply the microcontroller?

P0_2 voltage

Hi all,

A 4.7K pull-up resistor is used to connect the GPIO pin P0_2.We set the pin as high level input state,however,the voltage between the pullup resistor is not zero.So the resistor comsumes about 10 uA.
The 4.7K pull-up resistor connecting the GPIO pin P0_4 and P2_0 comsumes no current.

Should I use another pin to decrease the standby current?
